What is the HullWiper?
• Diver-free and environmentally
friendly
• Remotely Operated Vehicle (ROV)
equipped with water jets, designed
to clean up to 2,000 sqm/h
• Utilises salt water under high
pressure as the cleaning medium
• Collects pollutants from the cleaning
and disposes of in an
environmentally-friendly manner
• Can clean ships while taking on
bunker fuels or loading/discharging
cargo, saving valuable time
• Granted permission to clean vessels
in port
Cost effective & environmentally friendly hull cleaning technology

How does the HullWiper work?
While a vessel is in port, a GAC EnvironHull
support vessel comes either alongside or to berth.
ROV Supervisor gives the vessel staff a safety
brief. Team sets up the HullWiper ROV to start
the underwater cleaning process.
ROV operator on-board support vessel guides ROV
HullWiper to approach ship and once in position
engages cleaning mechanism.
Water jet pressure is adjusted to remove fouling
without compromising the vessel’s anti-fouling
coating. HullWiper cleans at an average speed of
1000-2,000 m²/hour, completing a full hull in
considerably less time than divers as the ROV has
no night time restrictions.
A clean (smooth) hull improves vessel speed and produces big savings on fuel
Residues and harmful marine organisms are then
disposed of ashore in an accepted and
environmentally approved manner, with all details
recorded in a waste material log.
Removed fouling is captured on-board the
HullWiper’s fouling retrieval units and only clean
water is released back into sea. Process is monitored
during the whole cleaning operation.

Saving time, money and environment Safety & environment
• No divers in the water means no risk of injuries or
casualties
• Organic grown retrieval system with all waste
disposed with environmentally approved methods
Hullwiper vs brushes
• Brushes remove significantly more anti-fouling
coating than HullWiper and this method doesn’t
create coating cavities
• Re-growth of organic material is generally 2-3 times
slower with HullWiper cleaning as opposed to
brushes
• HullWiper cleaning is faster than conventional
cleaning with brushes and works 24/7 so no delays
due to schedules
• HullWiper cleans ships alongside while loading/
discharging cargo so no need for deviation or down
time for a hull cleaning location
